Mesh geeration and user guide EnGrid

Hello guys, I think I need your help.

I’m working with OpenFOAM and I want to try EnGrid. I have two questions about it

First:
Where to find good information how to use the program? I only found on tutorial on Youtube from Calum Douglas.
https://www.youtube.com/watch?v=VwSXldG3ank&t=315s

Second:
The tutorial sounds good for me but the programm just doesn’t do what he says. For example he says right at the beginning to press p to open a window but nithing happens on my own Computer. Do others/ you also have the same problem?

I ran it as an administrtor
I joined all parts to a single part
I saved it as binary .stl -file (ASCII-option deactivateted, so I think its binary)

The text on the right side of EnGrid says the following:

secs. for class IOOperation: 53
cleaning STL geometry:
tolerance = 1e-010
The STL geometry seems to be clean.
secs. for class CorrectSurfaceOrientation: 0
removing 'stray' nodes
deleting 0 nodes!
secs. for class DeleteStrayNodes: 0
marking non-manifold edges
done.
updating node information ...
done.
swapping edges for surface triangles ...
loop 1/1
sub-loop 1: 0 swaps
secs. for undefined: 0
updating node information ...
done.
secs. for class FixCadGeometry: 0
secs. for class IOOperation: 11
OnChar p
OnChar s --> This is doing nothing...

Any Ideas?
Thank you in advance!

1- left click on surface (lets say on face )
2- press p (then red spot will seen in window)
3-press s then it will ask bc condition

above process you have do until and unless you haven't set all bc remember red spot imp

if not working please reply or try to install it again.
